Can you help me understand how % Ready is calculated within Foglight?  I am doing the calculation manually, and looking at the server in vCenter, and my numbers are way different than what Foglight is coming up with for % Ready.

I ran the report so the CPU Ready summation (average) for 1hour is 3612ms, and divide that by 20,000, and I see that %RDY is at 18%.  If I look at esxtop, %RDY comes up about the same, 18% ready.  However, in Foglight it is telling me it’s at 2.3% RDY for the same 1 hour time period. 

Any ideas ?
